Before your purchase a stove, consider what kinds of meals you would like to cook with it and where you will use it in the outdoors. Stoves vary in weight, size, fuel type, and how it works. Choosing a fuel type is key to choosing the best stove for your needs. Propane, butane or Isobutane canisters are convenient because they do not spill, do not require priming and burn clean. However, most of these canisters are not recyclable. Also, they add more weight to your pack because canisters must be carried out. Furthermore, butane will not work below freezing temperatures. White gas, on the other hand, can be poured into a re-fillable fuel container that attaches to many stoves. White gas is inexpensive, evaporates quickly if spilled, works down to zero degrees F, and does require priming. Note that it is hard to find white gas outside the U.S. Some stoves are interchangeable and can connect to propane canisters and white gas containers. This gives you some flexibility if your stove needs are varied.
